a1 OFFIQ RICHARD LABABRE, OF NEW ORLEANS, LOUISIANA, ASSIGNOR. T STANDARD LOOSE LEAF COMPANY, INC., 015 NEW ORLEANS, LOUISIANA.

. TEMPORARY BINDER.

To all whom it may concern 7 Be it known that I, RICHARD LABARRE, a citizen of'the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements. in Temporary Binders, of which the following is a specification.

This invention relates to temporary binders and more particularlyv to a form of lock to be used in connection therewith.

The principal object of the invention is to provide a binder for loose leaves having a locking device which is simple and efiicient,

which can be readily applied and removed and which cooperates with the cover members in such manner that when in operative position it is held against rapid removal.

Another object of the invention is the provision of a binder of this character having threaded posts and a readily removable nut for locking the sheets on the post which coacts with one of the cover members to prevent its accidental removal and to prevent the separation of the cover members.

Further objects of the invention will appear as the following specific description is read in connection with the accompanying drawings which form a part of this application, and in which Figure 1 is a perspective view of the binder when in closed position. Fig. 2 is a similar view in open position. Fig. 3 is a transverse sectional view on the line 33 of Fig. 2. Fig. 4 is a detail plan view of a part of one of the cover members. Fig. 5 is a perspective view of one form of locking nut. Fig. 6 is a similar view of another form of locking nut. Fig. 7 is a detail sectional view showing a permanent locking nut in position.

Referring moreparticularly to the drawings 1 and 2 represent the separate cover members hereinafter called the back and front respectively and both being provided with a hinged back portion indicated at 3 and 4c. The back portion 3 is provided, as shown, with a stiffening member, preferably a metal bar 5 to which is connected the sheet retaining posts 6 threaded throughout their length. The back section dis also provided with a metal reinforcing or stiffening strip which has formed therein the slots 7. These slots are made with an attenuated entrance 8 adapted to permit the passage of the post Specification of Letters Patent.

6 and an enlarged receiving portion 9 at their inner ends.

The locking. members each comprise a split nut 10, the halves l1 and 12 of which. are pivotally; connected together by a pin 13 eX- tenclingflthrough the radial ears 14. These ears are each provided with a shoulder 15 which. limits the opening of the separate halves and each half is cutaway as shown at 16 to provide a V-shaped opening leading nto the threaded portion 17 as will be read- 11y understood so that when the halves are closed, all that is necessary isto push. the nut against the post which will cause the openings of the parts to permit the entrance of the post. The halves may then be clamped around the post and the nut turned down on thepostuntil it engages. the back portion 4 which lies upon the top of the sheets as will be seen from an inspection of sections 1 and 2. Each half of the nut is provided with a depending semi-circular collar 18 which, when the halves are brought together, forms a circular collar whose sides are tapered so as to wedge into the opening or enlarged portion 9 of the slots 7.

' In the form of nut shown in Fig. 6 the shoulders 15 are omitted and each half of the nut is provided with a semi-circular groove which receives a portion of a bowed spring 19 adapted to normally hold the halves of the nut together. The nut is otherwise of the same formation as the-nut shown in Fig. 5. It will be readily seen that when either of the nuts shown in Figs. 5 or 6 are screwed down upon the back section 4, that the semi-circular collar portion will be wedged into the openings 9, thereby preventing the opening of the nut until the collar is released from the opening. When the nut is unscrewed upon the post sufliciently to relieve the collar from the openings 9, they can be readily removed by simply separating the halves. These nuts are used until the binder is full when they are removed and nuts similar to those shown in Fig. 7 screwed upon the post.

What is claimed is 1. A loose leaf binder comprising separate back members, one of which is provided with openings having attenuated entrances, posts carried by the other back member and arranged to pass through the entrances in the openings, nuts having hinged sections threaded upon the posts, means on the sections for limiting the swinging movement of the same while the nuts are being positioned upon or removed from the posts, and means on the nuts for cooperating with portions of said slots to prevent opening of the nuts and lateral displacement of the back members.

2. A binder comprising separate back members, posts carried by one of the back members, the other back member having slots with attenuated entrances, split nuts threaded upon the posts and arranged to clamp the back members together, and means on the nuts for cooperating with portions of said slots for holding the back members against displacement and preventing the nuts from opening.

3. A loose leaf binder comprising separate back members one of which is provided with openings having attenuated entrances, posts carried by the other back member and arranged to pass through the entrances into the openings, split nuts threaded upon the posts and adapted to be removed laterally therefrom, and means on the nuts adapted to fit the openings when the nuts are clamped upon the back members whereby the back members are held against displacement and the nuts held against opening.

4. A loose leaf binder comprising separate back members one of which is provided with openings having attenuated entrances, posts carried by the other back member and arranged to pass through the entrances into the openings, split nuts threaded upon the posts and adapted to be removed laterally therefrom, and a collar formed on the separate halves of the nuts and arranged to wedge or fit the openings whereby lateral displacement of the back members will be prevented and the nuts held against opening.

5. A loose leaf binder comprising separate back members one of which is provided with open slots, posts carried by the other back member arranged to engage the said slots, split nuts threaded upon the posts, springs for normally closing the nuts on the posts and means carried by the nuts for engaging the slots, said means coacting with the walls of the slots to prevent opening of the nuts and to prevent the lateral disengagement of the back members.

In testimony whereof I aflix my signature in presence of two witnesses.
